JOHN, L. PORTER, OF ST. LOUIS, MISSOURI.

WEATHER-STRIP.

Specification of Letters Patent.

Patented May 1 1, 1909.

Application led April 3, 1908. Serial No. 425,023.

To all whorn it may concern:

Be it known that I, JOHN L. PORTER, a

citizen of the United States, residing in the I 4 neath the door, said view being intended to downward from the said lower edge of the .invented new and useful Improvements in vitself to any unevenness in the door-sill 1n city of St. Louis `'and State of Missouri, have Weather-Strips, of which the following isn speciication.

This invention relates to certain new and usefulimprovements in weather stripsof a type adapted for application in various connections, kbut intended more particularly for use on the bottomof a door. When so placed it will, when the door is closed, rest upon the door-sill and prevent airfrom entering beneath the door.

The invention has for its'obj ect in addition to the general novelty andy simplicity of the construction, to provide a weather strip which may be readily secured on the lower edge of the door and which when so positioned will in operation automatically adapt manner as to be in contact with the door-sill throughout its length' and thereb r effectively shut oli the passage of air beneath the door. l

In the drawing: Figure 1 is a perspective view of the weather stri detached from the door; Fi 2 is a front viewA of a portion of a door wit my invention applied thereto, the door being closed and partly broken away, and the'strip resting upon the door-sill be such illustrate the manner in which the strip will` conform to the uneven surface of the doorsill; and Fig. 3 is across section through the lower portion of a door having my inventipn ap lied thereto. v

eferring now to the drawin the numeral 1 indicates the door, in the Iower edge of which near the inner side of the door, is pro-` vided a longitudinal groove 2, which extends from side to side of the door. If preferred, however, said groove could'stop short-.of the extreme edges of the door as will be obvious without illustration.

3 -indicates a spring-metal strip which is secured along oneside to thebottoin edge ofthe door, near the outer side of the latter, from which line of connection it extends door. The o posite edge portion yof this strip is suitab y bent, yas shown, to provide a longitudinal recess 4, extending throughout the length of the strip, said recess having substantially parallel walls, and the lower edge portion of the outer wall being provided throughout its length with a spring-metal wire 5, the material of said wall being simply bent or curled around said wire to incase the same. This wire materially assists in afford- E ing a springy character to the free edge portion of the strip to enable it to readily accommodate itself to the shape of the doorsill While at the same time insuring the return of the strip to its nor mal shape when the door is opened, so that the edge of the stri ma not lose its springy character and wil at a l times press into contact `with the door-sill. In order to ermit the bearing surface of the strip to yidld or bend at different points throughout its length I provide at suitable intervals throughout the strip slits 6, which are cut'through both walls of the pocket 4, and which extend from the top of said pocket to n/ear the lower edges of the same. By bending the metal strip 3 to form the pocket `4:, an upward projection 7 is provided which is received into the groove i? in the lower edge of the door, before referred to, and which projection works in said groove as thel door is opened and closed.

As is well known, the central portion of a I door-sill is subjected to the greatest wear, due tothe passing over of ersons entering through the door and ina vertently sera ing the door-sill with their shoes. If t e weather strip extended parallel to the lower edge of the door at alltimes, it is apparent that there would be a space at the central portion of the door which would not be closed by the -Weather strip. By reference to Fig. 2, it will be seen that, under the circumstancesalluded toabove, the central eiiet to thestrip and also to render its' operation noiseless, lI secure inthe pocket 4 a stri 8, which'may be of felt, or rubber, or ot er suitable material, and which projects below the edge of the strip-3 a suicient distance to form the actual contact surface of the weather strip.

As indicated above, 'my invention is not limited in application to a door, or to the r bearing material secured in sai bottom of a door, but may be applied to the appropriate edge, or edges, of windows, or screen-doors, and, in fact to any analogous device cooperating with a surrounding frame to eii'ect a closure, and whether swinging vertically or horizontally.

I claim:

1. In combination with a closure having a longitudinal groove in one edge thereof, a spring-metal plate secured along one of its sides to said edge and having at its opposite side an angular extension forming a pocket, and adapted to work in said groove, and bearing material secured in said pocket apd projecting beyond the outer face of said p ate.

2. In combination with a door provided with a longitudinal groove in its lower edge, a spring-metal strip secured along one of its sides to said lower edge of the door near one side of the latter and provided in its opposite side portion with an upward extension adapted to work in said groove, said upward extension forming a iocket, and

d )ochet and projecting below the lower face o said metal strip.

3. In combination with a door rovided in its lower edge with a longitudina groove, a spring-metal strip secured along one of its sides to said lower edge of the door near one side of the latter land provided at its o posite side portion with an upward extension adapted to work in said groove and forming a pocket extending throughout the length of t e strip, bearing material secured in said pocket and projecting below the lower face of said strip, said projecting portion bein provided throughout its length at suitab e intervals with vertically disposed slits.

4. In combination with a door rovided in its lower ed e with a longitudina groove, a spring-nieta strip secured alongone of its sides tosaid lower edge of the door near one side of the latter and provided at its opposite side portion with an u ward extension adapted to work 4in sai groove and forming a ocket extending throughout the length of the strip, bearing material secured in said pocket and projecting below the l lower face of said strip, said projecting porl tion being provided throughout its length i at suitable intervals with vertically disposed i slits, and a s ring-metal reinforcing wire secured in the ower edge of the outer wall of said pocket.

5. In combination with a door rovided in its lower ed e with a longitudina groove, a spring-nieta strip secured along onel of its sides to said lower edge of the door near one side of the latter and rojecting downward from the surface of t e lower edge of the door from such line .of attachment thereto, said metal stri having its opposite side portion suitably ent to provide un upward extension working in said roove and having substantially parallel wal s providing a pocket, and a strip of felt or the like secured in said pocket and projecting below the lower surface of said metal strip.

6. Aweather strip comprising a springmetal plate having one of its side portions bent upon itself in three directions to provide a longitudinal recess, having substantially parallel walls extending at right angles to the body of the strip and bearing material secured in said recess and projecting beyond the face of said plate.

7. A weather strip comprising a springinetal plate having one of its side portions bent upon itself to provide a longitudinal recess, the walls of said recess being slit at intervals throughout their length, and bearing material secured in said recess and projecting beyond the face of said plate.

8. A weather strip comprisin a springmetal plate having one of its si e portions bent upon itself to provide a longitudinal recess, the walls of said recess being slit at intervals throughout their length, a length of spring wire secured along the edge of the outer wall, and bearing material secured in said recess and projecting beyond the face of said plate.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
